The $25,000 Pattern Day Trader Rule Is Gone: How FINRA’s New Intraday Margin Rule Works

Timeline: from filing to phase-in deadline

Two details about the transition matter. During the 45 days between the Notice and June 4, every firm had to keep applying the old day-trading rules. The SEC order also says that during the interim period, firms may keep applying the old rules where appropriate, for example account by account, while they prepare. So on any date before October 20, 2027, your broker may be on the old PDT regime, the new intraday margin regime, or a mix.

What was removed

Per the SEC order and RN 26-10, FINRA deleted Rule 4210(f)(8)(B) and the related provisions. That removed:

• the definitions of “day trading” and “pattern day trader”, including the test of four or more day trades within five business days;
• the $25,000 minimum equity requirement for pattern day traders;
• day-trading buying power and its calculation;
• the special maintenance margin calls and the related 90-day “cash available” restriction tied to them;
• the two-business-day hold on funds deposited to meet PDT calls;
• related provisions in Rule 4210(b), (f)(10) for security futures and (g)(13) for portfolio margin, plus the old interpretations.

FINRA’s main stated reason was that the rule was built for a time of high commissions and end-of-day risk systems. Zero-commission trading and real-time risk tools changed that. The SEC order also notes commenters’ point that the PDT rules sometimes pushed traders to hold losing positions just to avoid a PDT flag.

What replaced it: intraday margin in plain English

The new framework sits in Rule 4210(a)(17)–(19) and (d)(2). It applies to every margin account except good-faith accounts and portfolio margin accounts, whether or not you day trade.

Three new terms

1. Intraday margin level (IML). At a given moment, the cash you could withdraw while still meeting regular maintenance margin. If you would have to deposit cash to meet maintenance, the IML is negative.
2. IML-reducing transaction. Any trade that lowers your IML, such as buying stock (other than to cover a short), shorting, or selling options. Withdrawals and expiring long options can also reduce IML.
3. Intraday margin deficit (IMD). For any day with an IML-reducing transaction, the largest negative IML right after any such transaction that day.

The key idea is that an IMD can exist even if you close every position before the bell. A day trade that would have broken maintenance margin at its peak still leaves a record.

How a deficit gets handled

• Satisfy it “as promptly as possible.” You can do that with net deposits, or with activity that raises your IML, such as closing positions. One deposit can cover several open deficits.
• The deficit expires after 15 business days. An IMD stays outstanding until satisfied or until the close of business on the 15th business day after it occurred, whichever comes first.
• Broker capital charge. If a deficit is still unmet after five business days, the broker must deduct it from net capital, for up to ten business days. That gives brokers a strong reason to collect quickly.
• The 90-day restriction. If you make a practice of not satisfying deficits promptly and a deficit is still unmet at the close of the fifth business day, the broker must stop you from creating or increasing short positions or debit balances for 90 calendar days, or until that deficit is satisfied.
• What doesn’t count toward a “practice.” Deficits no larger than the lesser of 5% of account equity or $1,000, and deficits the broker reasonably decides arose under extraordinary circumstances.
• FINRA’s safe harbor. Under interpretation 4210(d)(2)(D)/01, a customer who satisfies all but three deficits within three business days over a rolling 12 months is not considered to be making a practice of failing.

How brokers may run it

FINRA lets brokers choose their method. Per the SEC order and the June 4, 2026 interpretations:

• Real-time blocking. The broker monitors positions live and rejects orders that would create or increase a deficit. Customers of these firms should, in principle, never get an IMD.
• End-of-day calculation. The broker computes deficits once after the close, and may use end-of-day prices. For customers who don’t day trade or open same-day-expiry options, the result is comparable to a normal maintenance check.
• A hybrid, for example running the detailed calculation only on accounts with intraday exposure that end-of-day positions don’t show.

If the broker can’t prove the order of activities, it must assume the order that produces the largest deficit. Brokers can also apply stricter house requirements.

A simplified illustration

This hypothetical is ours, not FINRA’s, and ignores fees and house rules. Say your account has $6,000 of equity. Around midday you buy a position on margin. Immediately after that purchase, the maintenance margin required on everything you hold is $800 more than your equity, so your IML is –$800. You sell everything an hour later and end the day flat. Under the old rules, the trade would have counted toward the PDT test. Under the new rules, nobody counts trades, but you have an $800 intraday margin deficit to satisfy promptly. At a real-time broker, the purchase would likely have been blocked in the first place.

What stays the same

• Margin accounts still need minimum equity. Rule 4210(b)’s $2,000 minimum equity for margin and Regulation T’s initial margin requirements remain. FINRA’s investor page notes that with less than $2,000 you can still trade without leverage.
• Maintenance margin is unchanged. The 25% minimum on long equity positions still applies, and under the new rule it applies throughout the day, not only at the close. Brokers may require more.
• Cash accounts follow Regulation T, not the PDT rule. The Federal Reserve’s Regulation T governs cash accounts. Selling securities before paying for them (“freeriding”) can lead to a 90-day freeze under Reg T. The FINRA change doesn’t touch that. US equities settle T+1.
• Portfolio margin accounts get their own intraday-risk procedures. Accounts with less than $5 million in equity must hold margin for intraday risk that is substantially similar to end-of-day requirements.
• Short-sale rules (Reg SHO, including Rule 201’s short-sale circuit breaker) are separate and unchanged.
• Broker discretion stays. Brokers can still set higher requirements, limit leverage, restrict specific stocks (often low-priced or volatile small caps), or close accounts. The rule sets a minimum.

What changes for brokers

• They monitor every margin account, not only accounts flagged as PDT. Brokers no longer track day-trade counts or calculate day-trading buying power.
• They need written policies for the choices the rule leaves open: sweep-program balances, which prices to use, how to time “as of” adjustments, and how to treat spreads and same-day option exercises.
• Unmet deficits cost them capital. A deficit still open after five business days becomes a net capital deduction, and they must enforce the 90-day restriction where it applies.
• They pick a transition date. Any time between June 4, 2026 and October 20, 2027. Industry commenters warned that staggered adoption could confuse customers, which is why the switch date at your own broker is what counts.

What changes for small-cap day traders

• No trade counting. You no longer have to ration round trips to stay under three per five days in a margin account under $25,000, once your broker is on the new rule.
• Leverage is limited by risk at each moment. There’s no fixed “4x day-trading buying power” figure in the rule. What you can trade intraday is set by maintenance margin at each IML-reducing trade, plus your broker’s house rules. Brokers can also set stricter “house” requirements for individual securities or accounts (FINRA Rule 4210(d)(1)), and the SEC notes that many firms set maintenance at 30% to 40%, sometimes higher depending on the security (SEC Investor Bulletin). If your broker applies a higher house requirement to a stock you trade, usable leverage shrinks further.
• Same-day options expiry counts too. FINRA specifically cited zero-day options as intraday exposure the new rule is meant to capture.
• Discipline moves to deficits. Repeated unmet deficits now lead to the 90-day restriction, replacing the old PDT call.

FAQ

Is the $25,000 pattern day trader rule really gone? Yes, at the FINRA rule level. The SEC approved the change on April 14, 2026, and it took effect June 4, 2026. But brokers may phase it in until October 20, 2027, so your broker may still apply the old PDT rules to your account until it switches.

How do I know if my broker has switched? Check its announcements, margin disclosures and account agreement, or ask directly whether your account is under “intraday margin” or “pattern day trader” rules. As of October 5, 2026, we did not find a FINRA list of which firms have implemented.

Do I still need $2,000 to trade on margin? Yes. The $2,000 minimum equity requirement for margin accounts in Rule 4210(b) remains, alongside Regulation T initial margin. Below $2,000 you can still trade without leverage.

Can I day trade in a cash account without limits? The PDT rule never applied to cash accounts, and the new intraday margin rule doesn’t either. Cash accounts follow Regulation T: you can trade with settled funds, and selling securities before paying for them can trigger a 90-day freeze. Settlement is T+1.

What happens if I can’t cover an intraday margin deficit? You’re expected to satisfy it as promptly as possible. After five business days your broker takes a capital charge, and the deficit expires after 15 business days. If you make a practice of leaving deficits unmet past the fifth business day, the broker must block new short positions and new debit balances for 90 calendar days or until the deficit is satisfied. Small deficits (the lesser of 5% of equity or $1,000) don’t count toward a “practice.”

Does this apply to offshore brokers? FINRA rules apply to FINRA member broker-dealers. A firm outside the US that is not a FINRA member isn’t bound by Rule 4210, and it follows whatever rules its own regulator sets. Investor protections such as SIPC coverage and FINRA arbitration generally depend on the firm being a US-registered member. Check a firm’s registration on FINRA BrokerCheck before relying on any protection.

I use multiple brokers. Do they combine my activity? The new rule asks each member firm to compute deficits for each margin account it carries. Nothing in the rule text adds up activity across different firms. Each broker applies its own method and house rules.

Do overnight or extended-hours trades change this? The rule applies to IML-reducing transactions “during a day” but doesn’t spell out session boundaries. With 23-hour exchange trading targeted for December 6, 2026, ask your broker how it defines the day for intraday margin.
